I'm helping a friend migrate her wordpress server to GoDaddy, and I think I may have bitten off more than I can chew... I've never migrated a wordpress before. This page here is the Wordpress wiki for moving Wordpress when your domain isn't changing. It doesn't seem to complex, but I'm terrified of accidentally ruining this website and I don't understand a couple of things on the wiki.
The Wiki says
If database and URL remains the same, you can move by just copying your files and database.
Does this mean that I can just log in to her server from Filezilla and copy all of the files on the server? What does database mean, is that something separate from the files on the server?
If database name or user changes, edit wp-config.php to have the correct values.
This sort of goes with my first question.. What initiates a database name or user change?
Apologies for my ignorance, but after an hour or so of searching around for these answers I'm left just as confused.
Last but not least, is there anything else I should be aware of when migrating a wordpress? I'm a little nervous..
You are going to need to migrate you instalation in two parts.
Part 1 you already eluded to. You will need to copy the files from one server to another. I am guessing you know how to do this so I will not dive any deeper into it. If you do need more explanation, please let me know and I will edit the question.
Part 2 is what you mentioned but said you did not understand. Copying the database of wp install. Wordpress runs off of PHP and MySQL. The "files" part in part 1 is the PHP files (along with some html and css). You need to log into his MySQL server and do an export of his database. You should be able to export the database (How to export mysql database to another computer?) and import it into his new server on GoDaddy. (Error importing SQL dump into MySQL: Unknown database / Can't create database).
Just take things slow, follow the guides that I have linked and do not delete anything from the first server until everything is working on the second. Please let me know if you do not understand anything.
if you don't feel confortable with database exports and imports, try using plugins like:
http://wordpress.org/plugins/duplicator/
or
http://wordpress.org/plugins/wordpress-move/
Check his docs for info.
Luck!
• A database is literally a data base. It's where websites (and other applications) store their data eg. For Wordpress, it would be data such as posts, user information etc.
If you are using a cPanel setup then you would need to get access to it and navigate to phpMyAdmin which is the GUI for managing a database.
Now I'm not sure what type of setup you're using but that should be a start.
• A database has a connection server address (usually localhost), a database name, username and password. These are setup at the time of setting up a database.
When migrating servers, you would need to update those details in the wp-config.php file (I think around line 19 or so).
• The annoying part about migrating Wordpress to another server is the domain change as you have to update the old domain with the new domain throughout the database. However since you're not changing domain names, it should be a smooth ride as long as the new server supports PHP and has a database.

I'm relatively new to web development and I have some serious concerns about repairing/editing/fixing live site.
I use WordPress and its DB hold also configuration, so let's say that I need to do some work on website with e-shop. I will start website on my local with current version of DB from live website. But in few hours, when I'm done, I can't just overwrite live DB with my DB from local environment, because there are some new orders, posts etc.
How can we deal with this kinds of things?
Thanks everyone who will share his advice or experiences!
First youhave to make note of all the changes you are making in the files. You have to document it properly.
Next there are actually three cases
i) When changing the files alone
if you are changing just the files then obviously no need to change the database only the files needs to be updated. First no need to hack the core wordpress files as everything can be done through "actions" and "filters" method. I mean by creating a plugin so your core files are safe. https://codex.wordpress.org/Writing_a_Plugin
ii) When chaning the database alone
if you are chaning the database instead of deleting the entire datase and reloading you can simply alter the tables using "ALTER" command http://dev.mysql.com/doc/refman/5.7/en/alter-table.html.
iii) Changing both databse and files.
Follow (i) and (ii)
My WordPress files are downloading instead of executing on the server. I have tried changing the server but that does not solve the issue. I am sure it is happening from my WordPress files as the hosting runs other WordPress files smoothly.
I wish I could could provide the code but that isn't needed. Please guide me. Thanks.
I have only seen this happen when:
1) PHP is turned off or not installed on the server
2) The server needs to be reset
3) File names are not correct
4) The redirect script is not redirecting as it should
5) Links are not valid
The good news is most of these can be solved by you/your host. Call your host to ask them for help on verifying the PHP install/process. If everything is good (for instance, if you have another site on the same server that is working fine) then you need to verify file names. As this is WordPress and the file names are all pretty standard this isn't exactly likely but make sure there are no unwanted spaces and the file names are "something.php". With WordPress you may see a bunch of parameters passed through the URL so "something.php?blah=blah" Is fine too (no space between php and ?).
Check the link you are clicking. The file names might be good but the link may be bad. It might be as simple as fixing all the link URLs. From what I recall of WordPress, there is a built in method of linking to pages within the same WP site. I believe these are all based off the URL in the database so you may want to verify the URL in the database/config file to verify WP is sending them to the correct place. If they are not stored in the database and are instead, coded directly into the content, you may have to manually update every link to the correct URL.
Finally, if it is script or wordpress related you may want to consider a fresh WordPress install. The good thing about WordPress is all the good stuff is in the data base:
1) Make a backup of the data base
2) Trash your WP install completely
3) download and install new WP with desired plugins and themes
4) Restore database
If the last step breaks the server again, check URLs within the database: http://codex.wordpress.org/Changing_The_Site_URL
Your Host can usually help in backing up and restoring WP databases. Even godaddy (who does not support it) will often help you walk through the process (you really want to call the hosting team. As an ex-godaddy employee, those guys are the experts).
If this isn't enough information, please provide a link to the site. It will allow me to do some quick troubleshooting to determine the overall issue.
EDIT: Help for verifying php install
Create a php file with the following contents:
<?php phpinfo(); ?>
And upload it to your site
This will make information about your PHP install easily accessible
Note: DO NOT LEAVE THIS FILE UP PERMANENTLY AND DO NOT POST A LINK PUBLICLY, YOU DO NOT WANT RANDOM PEOPLE ON THE INTERNET ACCESSING THIS INFORMATION
If you can access the file and it loads up a bunch of information in a purple (I believe it is purple) table, your PHP install is up and running. If the file just downloads like the rest, contact your hosting provider.
I'm doing a manual WordPress update.
I backed up the database to a .sql file.
Is there any way to prevent write to database temporarily while still allowing read to the whole MySQL database?
This is to ensure
The backed up database is up to date
Users are still able to browse contents on my website without disruption (I will put up a maintenance notice that your posts will not be saved etc.)
Update
The upgrading activity is only used as an example here.
I'm planning to make some changes directly to the database as well and it will take a while.
I'm sure I have seen websites (famous one) showing that they were under maintenance and that my comments/ posts would not be recorded (no write) but I was still able to browse their websites (read is ok).
I thought it was quite a reasonable need, was it not?
I'm sure there must be a way to
Serve the caches of webpages (server-side) to users while not connecting the the database at all in up to a couple of hours (logging in/ registration will not available to users but that's ok)? How do you think I can achieve that then?
To lock out any visitors from posting comments and such, you can go into phpmyadmin, find the wordpress user account (DB_USER as defined in wp-config.php) and revoke its insert, edit and update privileges. But this will probably not degrade gracefully into user friendly error messages when they still try anyways ignoring your messages. And if you are doing an update through php script in the way the wordpress installs itself it may still need these privledges to make any necessary modifications like adding options to the options table.
What version are you upgrading from and to? I know the install took me all of 30 seconds, and I can't imagine there would be a huge change in database between updates. But then again WP can be highly customized and I don't know the extent your site deviates from the standard install.
Sorry I'm about to go to sleep so I won't go into depth but one way that works for sure is if you have two MySQL users, 1 for your website to read/write from and another to do your maintenance. Your first user, you can change his privileges temporarily to read only and that should work.
I have a very simple web page in PHP that uses a MySQL database to randomly feed a simple quiz that goes on forever as long as the user wants to keep answering questions.
I want to move this to my Android to be able to use it offline. I used jQuery Mobile to adapt the layouts to the smartphone. So now I want to move the database to a local database and remove all the need to an internet connection. I have absolutely no experience on Android development so if anyone can help me with a few questions, I'd appreciate it:
How can I store my existing database in the smartphone?
The only actions that the app performs on the database are selects. The information on the database will grow with time (not much, I just want to be able to add more records with time). Is there any tool I can use to manage the local database and add the information as I need (as I do now with PhpMyAdmin)?
The web page exists online right now, will I be able to run it locally as it is? (aka, PHP page with css and js files)
Thanks in advance.
1) Android databases are done in SQLite. I'm unsure exactly what the syntax difference between mySQL and SQLite is, but if a straight dump/import doesn't work, you could export to csv/import that way. For info on getting an external database packaged with an app, check Using your own SQLite database with Android applications. It's a very helpful guide to getting it set up.
2) I use a Firefox add-on, SQLiteManager. I hate doing it, as it's the only reason I have Firefox installed any more, but on *nix it's the best option I've found. It's either that, command line, or SQLiteMan, which I found feature-lacking. On other platforms, I can't comment.
3) I don't know if PHP has a good library for SQLite. If so, you'll most likely need to do some modification to work with that instead of mySQL. If you can get that running smoothly, you should be able to drop it into a webview. The other option is to redo it in Java.
Good luck!
I'm very, very new to PHP, so please bear with me. I'd like to configure my current website (whose files I've already converted to .php, and which I work on in Dreamweaver), so that every time I upload a new file to my server, the upload date will automatically be displayed in the article (WordPress and other CMSs do this, but I don't have the time to make a WordPress template similar to my current site layout).
The problem with the database is that it's hosted at 1and1, where remote access (i.e. via Dreamweaver) isn't permitted, and I have to use phpMyAdmin at my host's website, which is ridiculously slow. Whenever I want to, for example, create a table, I have to go through a ton of slow-loading pages.
Is there any way to automate this process, at least to some degree?
You could always build a simple PHP script which connects to your database and runs an SQL query. You could then just visit the page and the query would be executed.
Here's a tutorial on writing SQL and running it with PHP if you're not sure: http://www.tizag.com/mysqlTutorial/
PHPMyAdmin has a "SQL" tab, where you can enter text commands just as if you were typing them into your local mysql command line. If you're not sure where to find it, there's an image in this (otherwise irrelevant) tutorial. You can use this to create and modify tables, and also run queries of all kinds.
